Giagos tipped the scales at 155 pounds, while Magakian checked in
at 154.2. TPF 19 “Throwback Thursday” takes place Thursday night at
the Tachi Palace Hotel and Casino in Leemore, Calif. The event
streams live and free on Sherdog.com.

A member of the Elite Training Center, Giagos has won eight of 10
professional appearances, with six victories coming inside the
distance. The more experienced Magakian, meanwhile, has 19 pro
bouts to his credit; nine of the Hayastan Studio product’s 13
triumphs have come via submission.

Co-headliners Olaf Alonso (150.6) and Adrian Diaz
(149.8) were also cleared for their lightweight clash. An 11-time
WEC veteran, Alonso hasn’t competed since losing via doctor
stoppage against Kyle
Pimental in May 2009. Diaz has five wins in 9 fights, most
recently falling to current UFC talent Andre Fili
via third-round TKO more than one year ago.

Also of note on Thursday’s card is two-time Octagon veteran
Eddie
Yagin (145.4), who hasn’t stepped into the cage since upsetting
Mark
Hominick at UFC 145. “The Filipino Phenom” will lock horns with
Diego
Saraiva (145.4) in a rematch of a 2009 contest which Saraiva
won via doctor stoppage in round three.
